thanks delphi. can you explain the cos and sin portion a bit? i never really could understand why those are used to express a single side of a triangle

electric field strength is on the image - 20 N/C the issue here is, they want it in i, j k format

got that. that's where the 1.6 x 10^-4 came from.

1. 12.53 mL of a 1.74 M solution of AgNO3 are mixed with 1.43 mL of a 9.63 M solution of MgI2. Write equations for the reaction, ionic and net ionic. 2. Usually they give the products of the reaction but in this case we have to figure out what is produced. Where do I start? Thx

1. Find in the i, j, k format, the force on the +8 micro-Coulomb charge (pic att'd) F = 1.6 x 10^-4 Nno clue where to start thx
